The adapter works great in the cycle test so I really hoped it would do its job. I'm trying to upload a sketch to my standalone ATmega328P PU chip. However, since there is no DTR pin to the output, I had trouble connecting this device. I know the CH340 has a DTR pin and have seen pictures of people soldering a small wire from the DTR pin to the output, it seems a bit beyond my skillset. However, I have successfully connected it to the ESP8266-01 and it works great. I would like to see how to use this device with a standalone ATmega328P PU chip.
